Quality of life (QoL) in patients (pts) with squamous (SCC) NSCLC treated with nab-paclitaxel with carboplatin (nab-P/C) induction therapy: Interim analysis of the phase III ABOUND.sqm study.

64 Background: Recent data on QoL in pts with advanced NSCLC treated with platinum-doublets are limited. This interim analysis evaluated QoL in pts with SCC NSCLC treated with nab-P/C during the induction part of the ABOUND.sqm study. Methods: In the ongoing phase III ABOUND.sqm study, pts with advanced SCC NSCLC are treated with first-line nab-P 100 mg/m2 d 1, 8, 15 and C AUC 6 mg•min/mL d 1 (21-d cycles) for 4 cycles (induction). Pts not progressing after 4 cycles are randomized 2:1 to maintenance nab-P 100 mg/m2d 1 and 8 of each 21-d cycle + best supportive care (BSC) or BSC alone until progression. The primary endpoint is PFS from randomization to maintenance. QoL, an exploratory endpoint, was assessed using predefined PRO instruments, LCSS and EQ-5D-5L, on d 1 of each cycle. As the study is ongoing, this pre-planned analysis included data for QoL that were reported up to the cutoff date. Results: Of 128 pts included in this interim analysis, > 80% completed baseline (BL) + ≥ 1 post-BL PRO assessments...
